Ferromagnetic resonance in periodic particle arrays

Ferromagnetic resonance

Ferromagnetic Resonance

Ferromagnetism is used to characterize magnetic behavior of a material, such as the strong attraction to a permanent magnet. The origin of this strong magnetism is the presence of a spontaneous magnetization which is produced by a parallel alignment of spins. Instead of a parallel alignment of all the spins, there can be an anti-parallel alignment of unequal spins. This results in a spontaneous...

Properties and measurement of scanning tunneling microscope fabricated ferromagnetic particle arrays (invited)

The low temperature magnetic properties of arrays of scanning tunneling microscope @TM) fabricated ferromagnetic particles have been studied as a function of their dimension using a novel high sensitivity Hall magnetometer. Iron deposits with controlled shape and nanometer scale diameters (-25 nm) are formed using a STM to decompose a metalorganic precursor [Fe(CO)s] in the active area of the m...
